Dragon Fist (Katayama Shuu) Manga

ドラゴン・フィスト

Summary by SnoopyCool: Dragon Fist follows the exploits of a young dragon that is exiled from his clan after committing a terrible crime. This particular manga has been published one volume per year for the past 12 years, so the artistic style changes rather drastically as you read further on. It's a kind of chronicle of Katayama Shuu's growth as an artist (sorry, but I think mangas like that are pretty cool... you know, no need to read a new manga to see the new style, just keep reading the old one).
